CAMPBELL C. CARPENTER, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO U. S. LIGHT & HEAT CORPORATION, OF NIAGARA FALLS, NEW YORK, A CORPORATION 0F NEW YORK.

Application filed February The present invention relates to storage battery construction,

In storage batteries it is common to connect the plates of one polarity to a cell post, while the plates of opposite polarity are Connected to a similar cell post, which cell posts extend through a part of the cell to provide an outside connection. Inasniuch as there is considerable vibration between the cell and the plates within said cell. a great deal of difficulty has been experienced. due to the creepage of electrolyte along the cell posts, caused by such vibration.

An object of the present invention is to provide improved means for sealing the cell post to the cell whereby creepage of the electrolyte above referred to will be effectually prevented.

A further object is to provide a construction wherein a gasket may be employed between the post and the part. of the cell through which said post extends, whereby to etfectually seal said cell.

A further object is to provide a construction which is cheap and which is simple to assemble and disassemble.

Further objects will appear as the description proceeds.

Referring to the drawings:

Figure 1 represents in sectional elevation part of a storage battery cell, together with acell post extending therethrough, with improved means 'for sealing said cell to prcvent the escape of electrolyte according to the present invent-ion.

Figures 2 and 3 represent a moditication in sectional elevation and plan respectively.

Figure et represents a Jfurther modification.

Figures 5, 6, 7 and 8 show details ot a further modification.

Referring first to Figure l, a part ol a battery cell is indicated by the numeral 1l. This part may be the cover of the cell, though it is immaterial as far as the. present invention is concerned, whether the cell posts extend through the cover or any other part of the cell. The cell post is indicated by the numeral 2. The cell post 2 is provided with an annular outstanding portion 3 which is adapted to hold an annular gasket 4 in engagement with the part 1. Mounted on the opposite side of part 1 is a link 5 which should tit down over the cell post 2 with a sutliciently loose lit to permit the compression. of the gasket 4.

9, 1918. Serial No. 216,144.

In assembling the cell post within the part 1, pressure will be exerted downwardly on the link 5 whereby to put the gasket al under suitable compression. The link 5 will then be burned to the cell post 2 in the ordinary manner, whereby to be integrally united therewith. lnasmuch as the gasket l is held tightly against the under side ol the part 1, it will form an annular seal whereby to prevent creepage of electrolyte out of the cell around the post 2.

According to the embodiment of .the present invention illustrated in Figures 2 and 3, the cell post 2 is provided with an annular shoulder' (3. Between the shoulder 6 and the part 1 of the cell is located a` gasket- 7 which should be of annular form surrounding the cell post 2. The gasket 7 will be held in a state of compression between the shoulder G and the part 1 of the cell by means ot' a plurality of screws, 8, 8. Said screws 8, S, should be located within the boundary of the gasket 7 whereby said gasket 7 will torni an effective seal. Furthermore, the screw holes for the screws 8, 8, should not extend entirely d through the shoulder 6. Otherwise, electrolyte might escape around said screws 8, 8.

According to Figure 4, the cell post 2 provided ,with an annular outstanding portion 3, similar to that shown in Fig. 1. Said outstanding portion 3 is adapted to hold the gasket L1. rl`hc cell post .2 is provided with a circular slot 1st into which the part 1 will be locked. ln mounting the part 1 on the cell post 2 according to the embodiment` ot the invention illustrated in Figure 4t, the part 't will be softened by the local application ol' heat around the region which is to be mounted in the slotv 14. Due to the softening ot the part 1. the cell. post may be readily `torcezl therethrough and locked, with the upper shoulder provided by the slot 14 resting upon the upper part ot' the part 1. lVhen the parts are assembled in this position. the. gasket 4t should be in a state of compression.

According to Figures 5 to 8, the cell post is adapted to be tightly secured to the part 1 b v means of.I a bayonet catch. As shown in Figure 5, the cell post is provided with an annular' outstanding portion 3 which holds a gasket Il, as in Fig. 1. Above the part 1 the cell post may be provided with a pair of longitudinal slots 15, each ot which communicates with a slot 16 extending at an angle to the slot 15. A nut 17 will be prolill) llt) vided having a pair of teeth to ride in the slots 15.

17 on the cell post, said through a part of a revolution when the teeth 18, 18, are in proximity to the slots 16, 16, whereby the nut 17 will be locked against movement longitudinally of the cell post 2, after the manner ot a bayonet catch. It it should be considered desirable, the upper shoulders 18, 18, provided by the slots 16, 16, may be given a slight pitch, whereby turning` of the nut 17 will force said nut downwardly. A small notch 19 may be provided in each of the shoulders 18, 18, it d sired, in order to lock the nut against cir cular movement. According to the disclosure in Figures 5 to 8, the nut may be turned in either a clockwise or counter-clockwise direction for locking. Obviously, it is not necessary to provide more than one of these possibilities. It is also obvious that the showing of teeth and slots on post and nut may be reversed, it desired. F rtherm-ore, the pitch to the shoulders 18 and also the notch 19 may be omitted, if desired. Then the term bayonet catch is used herein, it is intended to cover broadly the construction of tooth and co-operating angularly placed slots.

The member 2 with its annular outstanding portion, need not be solid in construction, but may be provided with a longitudinally extending hole whereby to serve as an adapter to be mounted over the ordinary cell post.

lVhen the nut 17 is moved to its locked position, the gasket l should be in a stat-e ot' compression, whereby to form a tight seal. In disassembling the parts according to the disclosure in Figures 5 to 8, it will be nec essary only to release the bayonet catch, when the parts may be readily taken apart.

The described embodiments are chosen merely for the purpose ot illustration. Many modifications will occur to those skilled in the art. It is intended in this patent to cover all such modifications that fall wi thin the scope of the invention as defined by the appended claims.

IVhat I claimas new and desire to secure by Letters Patent of the United States is- 1.
